N.K. Cyborg

Trample, haste
Whenever N.K. Cyborg becomes the target of an ability or a spell an opponent controls for the
first time each turn, counter that ability unless
they have N.K. Cyborg deal 10 damage to them.
Discard an artifact card: N.K. Cyborg deals
damage to each creature your opponents control
equal to the discarded card's converted mana cost.
